The first file (002) works fine on my Sansa e200, but the second one doesn't play at all. This is a known problem, where long MP4/AAC files will not play at all or possibly crash Rockbox. The reason is that the decoder runs out of memory, because it doesn't handle some data tables needed for playback and seeking in a very efficient manner (it pretty much reads the tables verbatim from the file).

I can reconfirm this bug still exists (iPod Video 60 Gig) r18335 clean install. 02 does’t play (codex error)* and 03 spins disk indefinitely. I accidently left to room and when I picked up my iPod I Burt my finger**.
